Why cravings happen (and why they always end)

A craving is your brain noticing a gap between the nicotine level it expected and the level it found. It isn't a moral failure or a sign of weakness — it's a prediction error, and your brain is very loud about prediction errors.

The important part: cravings are self-limiting. Most peak within 3 to 5 minutes and fade whether or not you act on them. Vaping just teaches your brain that the alarm works, which makes the next alarm louder.

Every craving you ride out is data your brain uses to lower the volume. Twenty cravings in, the alarm is quieter. A hundred in, it's background noise.

Practical move: when a craving hits, timestamp it. Open the craving tool, start the timer, and watch the number go up while the feeling goes down. Seeing that gap close is what changes the belief that you 'need' it.
